Discussion

Densely lanate or woolly plants of Hulsea nana are referable to var. larsenii. Such plants may occur in distinct populations but can be found together with sparsely lanate and strictly glandular plants. The distribution of lanate to woolly plants appears associated with higher levels of insolation.
